Get SDT Rest API

For few deployments in production, api https://www.logicmonitor.com/support/rest-api-developers-guide/sdts/get-sdts/ is throwing bad request "{"data":null,"errmsg":"Bad request","status":1007}".  Will the msg bad request comes only when deleting the sdt which does't exist.

We do not have enough information to validate this point, can anyone please confirm on this?
